This invention relates in general to an imitation plaster constituted of sheet metal and more particularly to a rough texture plaster, for instance a rough texture plaster of the style of the so-called-Spanish plaster which is constituted of metal sheets.

In carrying out certain types of architec` ture and Certain schemes of interior decorating, it has been found desirable and advantageous to utilize for the walls and ceilings, rough texture plaster or so-calledvSpanish plaster. This type of plaster blends in well with the Spanish style of architecture and is becoming increasingly popular. In many instances it has been desirable to employ metal ceilings and metal side walls, as the ceilings and side walls so constituted have a great many advantages. But, heretofore, it has been impossible to utilize metal ceilings and sidewalls where a rough texture or Spanish style of interior surfacing was desired as the only known means of affording such ceiling and side walls surfacing was to work up this texture in the plaster prior to its setting.

One of the principal objects of the present invention is to provide an imitation plaster constituted of sheet metal and yet having its external surface of rough texture or of Spanish plaster forma-tion. While the s ide walls and ceilings so constituted are made up of metal sheets,.the sheets are so constructed and so assembled that the resulting side walls and ceilings present apparently a single continuous surface having the irregular formation, the rough texture, and the other characteristics of the.ordinary Spanish plaster or of other style rough texture plaster' simulated.

In carrying out the present invention, metal sheets are stamped by means of dies so that their external surfaces are of irregular relief and intaglio formation ofthe character of rough texture plaster. One side edge of each sheet and one end edge thereofare oiset while the other side edge and the other end edge lie in the same mean plane as the major portion or the body of the sheet. rIhe side edge portions are of identical irregular formation and the same is true of the end edges so that when the side edges and the end edges ofadj acent sheets gverlap, the features of their relief and intaglio :formation will register and intert to conceal the joints and give thev appearance of a continuous plaster surface.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly' pointed out in the appended claims, reference being had to the accompa'nying drawings forming a part of this specification, and in which:

Figure 1 isa fragmentary plan view show- 'ing a portion of a ceiling made up of metal sheets embodyin the present invention;

Figure 2 is a etail plan view of one of the sheets;

Figure 3 is a fragmentary sectional view taken on line 3-3 of Figure 4;

Figure 4 is a fragmentary sectional view taken on line 4-4 of Figure 3; and

Figure 5 is a diagrammatic view showing the manner ofreproducing opposed edges of the original or matrix from which the sheets are produced.

Referring to the drawings, the numeral l designates a section of the imitation plaster embodying the present invention. As illustrated, this section l consists of a sheet of metal stamped by means of dies to have the relief and intaglio lformation of rough texture plaster or the so-called Spanish plaster. In other words, throughout its entire extentb portions of the metal of 'the sheet are dis-' placed inwardly and outwardly to provide proininences and' recessions or ridges and valleys of irregular formation, and of artistic character which blend into each other with a pleasing and decorative eiiect. While one design or one type of rough texture plaster is shown, it is obvious that the style or design of the rough texture may be varied. One side edge portion 2 of each sheet is offset inwardly from t-he mean or average pla-ne of the main portion of the sheet as shown to advantage in Figures 2 and 4, while the other side edge portion 3 thereof lies in the same mean plane as the body portion or major portion of the sheet. These side edge portions 2 and 3 are of identical corresponding formation, that is v vto say,

of one correspends exactl sions or relie and intaglio formation of the other. With this construction, when the side edge portion 3 of one sheet is positionedv to overlap the side edge portion-2 of an adjacent sheet, the prominences and recessions of the edge' portion 2 will register and snugly interit with the prominences andrecessions of the edge portion 3. One end portion 4 of each sheet is offset inwardly in a manner similar to the offsettingof the edge portion 2 while the other end portion 5 lies in the mean plane of the sheet and these end edge portions 4 and 5 are of identical or corresponding formation to register and interit with the overlapping end edges of adjacent sheets.

The sheet metal sections l are assembled in side wall or in ceiling as illustrated in Figure 1, the edges of the sheets overlapping and interfitting so that the surfaces of the individual sheets blend into an apparently single vcontinuous surface having the irregular formation, the rough texture, and the other characteristics of Spanish plaster. An ornamental border 10 may surround the sheets when assembled in a ceiling.

In producing the sheet metal sections embodyi this invention, origina section of plaster, mud, clay or other plastic of proper consistency, is worked up by an expert plasterer and is of the size of the sheet metal section to be produced. Of course, inf this original the edges are' of diverse irregular formation. To obtain identity or correspondin formation between the two side edgs, an between the two end edges, an impression is made of one side edge edge.

-portion O ortion and of one end edge portion and the side edge portion and the end edge portion of which the impression is made are reproduced and replace respectively the other side and end edge portions of different formation so that now in the original we have corresponding side edge portions and corresponding end edge portions. In other words, one of the diverse side edges is cut away and replaced by `a reproduction of the other side edge and the reproduced side edge portion is then blended in with the maj or portion of the original. Likewise one of the diverse end edges is' cut away and replaced by a reproduction of the other end edge. But the reproduced edge portion now has its previous outer edge or margin located in the body of the matrix and the final margin or outer edge of the reproduced edge portion corresponds in structure and formation to a portion of the body located inwardly of the opposite This will-be clear from the diagram shown in Figure 5. The original side edge of the matrix M is cut away along the line S. Thereproduction RO of the side edge portion 2 is now placed in the space the rominences and recessione or the relief and intaglio formation to the prominences and recesa matrix, that is an' inea-154 previously occupied by the original edge portion O but the edge a now lies in the bo y of the matrix and the edge b is the marginal edge. The body of the matrix is then blended in with the reproduced edge portion RO so that the features of the edge ortion R0 have continuations in the body o the matrix. The end edges are made to correspond in the saine Iway. From the original or matrix having these characteristics, the dies are produced in the usual manner and these dies are employed to stamp having the characteristics of Spanish plaster and the edge portions adapted to intertit and to blend the features of one sheet into thefeatures of another. stamped orotherwise fashioned to have thc relief and intaglio formation of rough texture or Spanish plaster, the resultin structure is constituted of a multiplicity o prominences and recessions, or ridges and valle s, and the ridges and valleys are of irregu ar out sheet metal section.;

`W ith a metal sheet and varying occurrence and of varying or 'similar featuresv of the same size and shape and of the same location las above described, whereby the r`id es and valleys of the meeting edges of a jacent sheets register and interit snugly lwhen overlapped in the assembly.
